Can't get maximum from int and double

[rajhansk]

Write your question here.

  
#include <iostream>
#include<algorithm>
using namespace std;

int main()

{  int i=10;


    max(1,i);
   cout<<"The max(11.1,i) is "<<max(11.1,i);
    return 0;
}

it is showing an error.

#include <iostream>

namespace my
{
    template < typename A, typename B > // note: unlike std::max(), returns a prvalue
    constexpr auto max( const A& a, const B& b ) { return a<b ? b : a ; }

    template < typename FIRST, typename... REST > // note: unlike std::max(), returns a prvalue
    constexpr auto max( const FIRST& first, const REST&... rest ) { return max( first, max(rest...) ) ; }
}

int main()
{
    std::cout << std::fixed << my::max( 11.1, 12 ) << '\n' // 12.00 (common type for double and int is double)
                            << my::max( 11.1, 12, 123LL ) << '\n' // 123.00
                            << my::max( 11.1, 12, 123LL, 'A', short(1234), 7.9f ) << '\n' ; // 1234.00
